I think there used to be an advisory of about 10% plus 3 mph, but they have probably changed that now to 70 +0.1 mph.

Speedo reads 3mph fast at 70 mph. It was showing about 75mph when the camera van was spotted, so my speed must have been 72 mph.

Usually have Waze switched on for alerts, but not today.

Fortunately I have never social media'd anything that is now deemed inappropriate, so if I appeal to the ECHR, that should let me off a custodial sentence.

The law is that if you exceed to speed limit at all you can be prosecuted, you are referring to the well known advisory 10% +2. which is just that advisory, so normally over 79mph is normal BUT you can be done for less.

78 on Speedo never had a ticket. Seen plenty of money grabbing bds safety cameras too.

I would be literally shocked if that results in any kind of motoring conviction!

10% +2 is where they start prosecuting so 77mph can get you a fine, if they play by the advisory limits. But more likely an SAC if you haven't done one for 3 years.

Barney Walsh got caught averaging 58 in a temporary 50 zone on the M4.
So, 10% +2 sounds about right.
I would imagine that his Mercedes SUV's speedo was pretty accurate.
Three points & £185 fine.
(Unfortunately that made it twelve points on his licence... Resulting in a six month ban.)

10% is to allow for device tolerance. I'm sure I'd read on here asking for proof of those saying they'd been done for 32 in a 30. Nobody ever did, this is often bandied about by people on SAC courses. A friend of mine (genuinely, not me!), recently got a ticket for 86 mph on the M5 and for once, a driver said 'fair cop.' He must have been indicating over 90 mph.

Even though he was just on the cusp of doing a course, he took the 3 points and £100 fine. I did one last summer, it cost £100. 40 in a 30 near Telford. rolleyes

Here's the guidelines:

Thank you all for your replies.

In recent years I have tried hard to adhere to all speed limits.
The reason is not points or licence, but by having a car collection I never want to be paying loaded premiums on six policies for 5 year periods. Insurers ask about convictions during the past 5 years. Think points remain in force for 3 years. Under some circumstances, insurers could pocket 10 times the amount of the fine, although they probably do not load premiums for just 1 conviction.

If you visit Wales you can play the 20 mph game. Set cruise control to 19mph. See how many cars you can gather in the queue behind you, when in a 20 mph limit on a straight, wide, deserted road. Award yourself extra points, for each following driver who cannot stand it any more and eventually decides to overtakes you. smile

.or just dab the speed limiter on at 25 mph.
(I don't know any 20 mph roads that are straight, wide, and deserted)..

Surely this should he a sticky by now? It's been asked enough times.

79mph is prosecution speed.10% + 2mph is the speed that they have you at, not the safe speed.

The safe speed could be 200mph. Limits were introduced because many cannot differentiate between a safe 26mph and an unsafe 31mph or 46mph.

I think safe is subjective. The M1 had it speed limit introduced in 1965 , but cars have improved hugely. The percentage of fates accidents is very low and may 85mph would be ok.

Culture was very different in 1965. British population was typically ambitious, had a sense of urgency and was willing to take calculated risks.

Today we live in a cosseted society where the state has removed a great deal of personal responsibility, safety is paramount and the population has become compliant, apathetic and lazy. All speed is dangerous now. The Green's policy of 55 mph motorway limit is ideal for Britain in 2026. All part of our managed decline.

A single speed limit contravention on your record is highly unlikely to materially affect your premiums, btw.

I also enjoy the 20mph game. Especially when followed by accelleration to 3 figures as soon as reaching the national.

A narrow 2 lane road with NSL near me ran alongside a river. After a couple of fatals where cars ended in the river, the speed limit was reduced from 60 to 40 for safety reasons.
This caused a huge outcry, along the lines of "why do I have to drive so slowly?"
I calculated that to drive the stretch of road at 40 took about 30 seconds more than doing it at 60. The trip from town to town took 20 mins and people were furious at spending an extra 30 seconds!!

Five years down the line nearly all drivers stick to the 40 with no problems.

But my calculations highlight the fact that doing that extra few mph, in the grand scheme of things, saves you very little time, but can lead to a conviction.

I also enjoy travelling at the speed limit (ROSPA Gold, IAM Masters) to see what happens behind me. Usually I am at the front of a queue of traffic. However, I will admit that when I am following a vehicle at the speed limit, I do occasionally get frustrated and mentally urge him/her to go faster, a habit left over from my sales repping days.

And all rollercoasters should be flat with gentle curves and not exceed 4 mph.

No, it is not a left over from anything, except a lack of anticipatory forethought...

It's a well known fact that going faster on road journeys makes no significant difference to the time taken.

Which is why we walk everywhere and get there at the same time.
